Definitions

  • This invention relates generally to the field of intraocular lenses (IOL) and, more particularly, to accommodative IOLs.
  • the human eye in its simplest terms functions to provide vision by transmitting light through a clear outer portion called the cornea, and focusing the image by way of a crystalline lens onto a retina.
  • the quality of the focused image depends on many factors including the size and shape of the eye, and the transparency of the cornea and the lens.
  • the lens is held in place within the posterior chamber of the eye by a membrane known as the capsular bag or posterior capsule, immersed in the aqueous humor.
  • the shape of the lens and the refractive index of the lens relative to the aqueous humor determine where light rays are focused onto the retina.
  • IOL intraocular lens
  • the natural lens multifocality of distance and near vision is provided by a mechanism known as accommodation.
  • the natural lens early in life, is soft and contained within the capsular bag.
  • the bag is suspended from the ciliary muscle by the zonules. Relaxation of the ciliary muscle tightens the zonules, and stretches the capsular bag. As a result, the natural lens tends to flatten. Tightening of the ciliary muscle relaxes the tension on the zonules, allowing the capsular bag and the natural lens to assume a more rounded shape. In this way, the natural lens can be focused alternatively on near and far objects. As the lens ages, it becomes harder and is less able to change shape in reaction to the tightening of the ciliary muscle. This makes it harder for the lens to focus on near objects, a medical condition known as presbyopia. Presbyopia affects nearly all adults over the age of 45 or 50.
  • IOL intraocular lens
  • bladder or bag-like intraocular lenses that consist of an outer flexible skin filled with a viscous gel. The resulting lens completely fills the capsular bag and is very soft and pliable, much like the natural lens. See for example, U.S. Patent Nos.
  • An accommodating intraocular lens (AIOL) adapted for implantation into a capsular bag includes an outer shell, a valve, and a force transfer assembly.
  • the outer shell includes at least one surface modification on at least a periphery of the outer shell to promote bonding with the capsular bag.
  • the valve is configured to permit injection of a fill material.
  • the force transfer assembly in the outer shell is adapted to transfer forces from the capsular bag to change the shape of the filled outer shell in response to changes in capsular bag shape.
  • FIG. 1 is an enlarged cross-sectional view of the lens according to a particular embodiment of the present invention.
  • FIG. 2 is an enlarged cross-sectional view of the lens of FIG. 1 showing the lens implanted in a capsular bag.
  • FIG. 3 is an enlarged cross-sectional view of the lens of FIG. 1 showing the lens implanted in a capsular bag and material being injected into the lens to approximate the unaccommodated state.
  • FIG. 4 is an enlarged cross-sectional view of the lens of FIG. 1 showing the lens implanted in a capsular bag and material being removed from the lens.
  • FIG. 5 is an enlarged cross-sectional view of the lens of FIG. 1 showing the lens implanted in a capsular bag and being in the accommodated state.
  • FIG. 6 is flowchart showing a method of implanting an inflatable accommodating lens according to particular embodiments of the present invention.
  • FIG. 7 illustrates a dual-optic accommodating IOL according to a particular embodiment of the present invention
  • FIGs. 8A, 8B, and 8C illustrates various embodiments of a dual-optic AIOL according to particular embodiments of the present invention as viewed along the optical axis;
  • FIG. 9 is a flowchart showing an example method of implanting a dual-optic AIOL according to particular embodiments of the present invention.
  • FIG. 10 illustrates a peripheral band usable in conjunction with various embodiments of the present invention.
  • Various embodiments of the present invention may provide an improved accommodating lens by promoting adhesion of the capsular bag around mechanical features of the accommodating IOL. This provides a more robust mechanical connection between the bag and the IOL to allow the flattening and relaxing of the bag, as opposed to the force of the ciliary muscles, to move the lens.
  • the changes in shape of the capsular bag are in turn used either to deform the lens to produce a power change (akin to the accommodation of the natural lens) or to produce a change in IOL power by separating two optical elements.
  • a lens 10 according to a particular embodiment of the present invention generally consists of an outer shell 12 defining internal void 13 which contains and interior fill material 14.
  • the outer shell 12 is preferably formed in any suitable overall diameter or length, for example, around 10 millimeters, for implantation in the capsular bag of the eye.
  • the outer shell 12 preferably is made from a soft, foldable material that is inherently resistant to the formation of posterior capsular opacification ("PCO"), such as a soft acrylic.
  • PCO posterior capsular opacification
  • the material of the outer shell 12 may be relatively more elastic than the capsular bag, so that outer shell 12 can be moved by the capsular bag with relative ease.
  • the outer shell 12 contains a fill valve 16 allowing fill material 14 to be injected into or removed from void 13.
  • the outer shell 12 may also include a force transfer structure, such as a plurality of stiffening radial ribs 18 having an appropriate spacing, e.g., 30°, and/or may be attached to a peripheral band surrounding the lens 10 (as described in greater detail below).
  • a force transfer structure such as a plurality of stiffening radial ribs 18 having an appropriate spacing, e.g., 30°, and/or may be attached to a peripheral band surrounding the lens 10 (as described in greater detail below).
  • the lens 10 also includes living hinges 21 at the periphery, so as to facilitate the shape change of the surfaces.
  • a peripheral band may be coupled to the living hinge assembly to transfer forces from the capsular bag into actuation of the living hinges.
  • the outer shell 12 may also contain sharp peripheral corners 20 designed to prevent equatorial cell proliferation on the optical surfaces of the lens 10, but cell adhesion is preferably encouraged around the hinges 21 at the periphery of the lens to improve the mechanical efficiency of force transfer between the capsular bag and lens 10.
  • At least part of the outer shell 12 is coated with surface modification 22, which may include coatings, texturing, or other suitable variation designed to promote protein adhesion.
  • coatings include complementary proteins, growth factors for the capsular bag, chitin or other organic chemicals used in signaling cell growth conditions.
  • the polymer structure used to form lens 10 may be protein- fortified, so that the lens material itself has a surface that encouraged protein bonding.
  • Other suitable surface modifications include nano-channels or other structures allowing cellular interpenetration into the lens structure. Such structures may also include coatings or treatments to promote cell growth and binding within the interpenetrating cell/lens network. Still other suitable surface modifications include the use of biocompatible adhesives.
  • Fill material 14 preferably is a liquid, gel, or low molecular weight polymer with a refractive index greater than that of the surrounding aqueous humor.
  • Such materials may include (but are not limited to) silicone oil, perfluoron, and cross-linked or non-cross-linked polymer gels. It is also preferable to minimize losses of fill material 14 due to diffusion, so outer shell 12 should preferably be relatively impermeable to fill material 14 and the surrounding aqueous humor.
  • lens 10 may be implanted in capsular bag 24 in an unfilled state. As seen in FIG.
  • internal void 13 is then filled with fill material 14 through valve 16 using an appropriate instrument, such as cannula 26 so that lens 10 approximates the shape of the natural lens in a disaccommodated state, which results in anterior surface 30 of outer shell 12 being relatively flat.
  • an appropriate instrument such as cannula 26
  • the anterior surface 30 changes shape considerably during accommodation while the posterior surface remains relatively unchanged in shape, but alternative embodiments could have both the anterior and the posterior surfaces changing shape to a lesser or greater degree.
  • One advantage of thickening the posterior surface or making the posterior surface relatively more rigid is that the posterior surface could be relatively fixed in order to more easily allow aspheric and/or toric correction to be used in lens 10. Diffractive and/or multifocal optics could be incorporated into the surface as well.
  • lens 10 When lens 10 is over-filled, zonules 28 are in a relaxed position. Lens 10 is left in this over-filled condition for a period of time sufficient for protein adhesions to form between outer shell 12 and capsular bag 24, e.g., 2-4 weeks. As best seen in FIG. 4, after protein adhesions have formed between outer shell 12 and capsular bag 24, sufficient filler material 14 is removed from void 13 through valve 16 for lens 10 to adopt the shape of a disaccommodated lens, as best seen in FIG. 5, with zonules 28 in tension and anterior surface 30 having a more rounded shape relative to the overfilled state, as shown by arrows 32.
  • the lens 10 may be also mechanically biased toward the accommodated state, so that when the capsular bag relaxes, the default tendency of the lens 10 is to restore to the accommodated state.
  • the living hinges 21 may have a spring action that tends to urge the anterior surface of the lens 30 into the accommodated shape.
  • FIG. 6 is a flowchart 100 showing an example implantation method according to particular embodiments of the present invention.
  • an inflatable accommodating lens (“AIOL") is provided with a surface modification to promote protein adhesion with the capsular bag.
  • AIOL inflatable accommodating lens
  • the AIOL is implanted in an unfilled state.
  • the AIOL is overfilled to facilitate contact with the capsular bag.
  • the capsular bag is allowed to heal around the AIOL for sufficient time to allow bonding between the capsular bag and the AIOL.
  • fill material is removed from the AIOL to reach a disaccommodated state for the AIOL.
  • FIG. 7 is a cross sectional view of a dual-optic AIOL 200 according to another embodiment of the present invention.
  • dual-optic refers to an AIOL including at least two optical elements, but such a dual-optic AIOL could include additional optical elements as well.
  • the dual-optic AIOL 200 includes an anterior optical element 202 and a posterior optical element 204.
  • one of the anterior optical element 202 or posterior optical element 204 has a positive power, and the other has a negative power so that the difference between the powers is relatively large and a change in spacing between the optical elements 202 and 204 produces a significant change in overall optical power.
  • One or both surfaces may also include aspheric, toric, diffractive, and/or multifocal correction as well. While both optical elements 202 and 204 are shown within the capsular bag, the AIOL 200 could include a sulcus-fixated anterior optical element 202 or even an
  • the AIOL 200 also includes interlocking features 206 between the optical elements 202 and 204.
  • Interlocking features 206 are located peripherally around the optical elements 202 and 204, and the interlocking features 206 also include surface modifications, such as the ones described above, to promote bonding of the capsular bag to the interlocking features 206.
  • Interlocking features 206 may be formed integrally, so that the entire AIOL 200 is a single piece, or they can alternatively be complementary features attached to their respective optical elements 202 and 204 so that the interlocking features 206 are connected to one another before or during implantation. While the interlocking features 206 are illustrated in an integrated living hinge configuration, other arrangements could function suitably as well, including arrangements using a hook-and-clasp or hinge pin. In the illustrated embodiment, the interlocking features 206 are configured to hold the optical elements 202 and 204 spaced apart from one another in the disaccommodated state to prevent adhesion.

  • the interlocking features 206 may include spring windings that are twisted by pulling outwardly on the interlocking features 206.
  • the interlocking features 206 release the stored mechanical energy to force the optical elements 202 and 204 apart, increasing the optical power of the AIOL 200 to provide accommodation.
  • the capsular bag should be bonded firmly to the interlocking features 206 in the disaccommodated state.

  • Peripheral band 400 serves to improve the mechanical connection with the capsular bag by preserving the tension in the anterior and posterior zonules as the capsular bag heals around the lens 10.
  • One difficulty that can arise with accommodating !OLs generally is that the AIOL can be somewhat flatter than the natural lens. This causes the more anterior and posterior zonules to be in greater tension as the capsular bag heals around the IOL than they would be around the natural lens.
  • the peripheral band 400 has sufficient width to span the area of the capsular bag where the zonules are attached, thus preventing the capsular bag from flattening in this area and preserving the zonular tension. This advantageously improves the force transfer from the capsular bag.
  • the peripheral band 400 can also be attached to the living hinges 21 illustrated, for example, in FIG. 1 , to provide additional leverage for the capsular bag forces to change the shape of the lens 10.
  • the peripheral band 400 can also be made of an elastic material that is mechanically biased toward the accommodated state, allowing the lens 10 to more easily restore to an accommodated position when tension in the capsular bag is relaxed.

  • the peripheral band 400 is mechanically connected to lens 10 or to the interlocking features 206 of dual-optic AIOL 200 so as to preserve a robust mechanical connection between the capsular bag and the movement of the AIOL.
  • This mechanical connection can be made, for example, by sizing the peripheral band 400 so that it fits snugly around the AIOL, by adhering the peripheral band 400 to the AIOL using adhesive, or by co-polymerizing or otherwise integrally forming the peripheral band 400 with the AIOL.
  • the peripheral band 400 can also include a sharp corner for prevention of PCO.
